The mini marigolds that I planted in the window planter at work about ten days ago are starting to come up. So is something I didn’t plant — see the seedling in the lower right corner?

It looks like a nasturtium; if so, it is either from a seed that I planted that didn’t germinate, or from a seed produced by the plants that were in this container for the past two years. It looks like there is another coming up at the back of the photo. The marigolds are the smaller seedlings in the middle of the photo. These nasturtiums will join the petunia and cosmos flowers in the “volunteer brigade” in my office.
